The clinical picture of central retinal artery occlusion is well known. Little is known, however, about the clinical picture of occlusion of the posterior cilliary arteries. The effects of such condition have been investigated by Hayre(1972) with the experimental occlusion of the various posterior ciliary arteries individually or together in rhesus monkey. The authors have experienced a case of 21 years old woman with the visual field defects developed by the human posterior ciliary arterial occlusion via a pathologic embolic process. A bridf review of the related literatures is presented.

BACKGROUND: Pathogen inactivation (PI) is a proactive approach to overcome the limitations of the current testing system and donor questionnaires. Effect of PI on non-leukoreduced platelet rich plasma derived platelets (PRP-PLTs) suspended in plasma has not yet been evaluated. This study was conducted in order to evaluate the effect of PI on the quality of non-leukoreduced PRP-PLTs suspended in plasma. METHODS: PRP-PLTs treated with the Mirasol PRT System and the Intercept Blood System were tested for PLT count, blood gas, PLT activation, and apoptosis on days 3, 5, and 7 of storage. RESULTS: PLT number showed a decrease after PI. No difference in pH was observed until day 5. At day 7, PLTs treated with Mirasol had a lower pH value (6.5), however, it satisfied the quality control criteria. PLTs treated with Mirasol had a lower pO2 compared to pre-inactivation PLTs. pO2 during storage differed significantly between the two PI groups. pCO2 showed a decrease after inactivation and both groups showed a significant difference, compared with the control. PLTs treated with Mirasol had increased P-selectin expression after inactivation; however, difference of P-selectin during storage was not significant compared to the control. P-selectin of PLTs treated with Intercept was significantly different compared to those treated with Mirasol and control. Annexin V showed an increase after inactivation in Mirasol treated PLTs and difference during storage was significant compared to control and Intercept. CONCLUSION: As both PI systems showed satisfactory pH values, the criteria showing a high correlation with in vivo PLT viability and generally applied to monitor quality of PLTs, quality of PRP-PLTs after PI appears not to be negatively affected.
